Signaling radio transmission mapping types

A wireless device configured to receive resource allocation information from a network node, the wireless device comprising a radio interface and processing circuitry configured to:

• receive an index indicating radio resource allocation information for a wireless transmission, the radio resource allocation information indicating one or more time-domain resources for the wireless transmission and a mapping type for the wireless transmission, wherein the mapping type refers to a reference signal placement within the wireless transmission, wherein the index identifies the radio resource allocation information of a predefined set of radio resource allocation information;
• use the index to determine the radio resource allocation information;
• and
• interpret the radio resource allocation information to determine a mapping type for the wireless transmission.

A method in a wireless device for receiving resource allocation information from a network node, the method comprising:

• receiving an index indicating radio resource allocation information for a wireless transmission, the radio resource allocation information indicating one or more time-domain resources for the wireless transmission and a mapping type for the wireless transmission, wherein the mapping type refers to a reference signal placement within the wireless transmission, wherein the index identifies the radio resource allocation information of a predefined set of radio resource allocation information;
• using the index to determine the radio resource allocation information;
• and
• interpreting the radio resource allocation information to determine a mapping type for the wireless transmission.
